Abstract
Description
印刷デバイスは、印刷媒体(例えば、用紙、フォトポリマー、プラスチック、複合材料、金属、木材など)に印刷物質(例えば、インク、トナーなど)を転写することにより、印刷媒体上にマーキングを形成する場合がある。印刷デバイスは、印刷媒体上にマーキングを形成するために、印刷ジョブのページ記述言語をレンダリングする場合がある。更に、印刷デバイスは、印刷媒体上にテキスト、イメージ、モデルなどの物理的表現を形成しながら、印刷媒体上に隠しマーキングを形成する場合がある。本明細書で使用される限り、用語「印刷デバイス」は、物理的印刷媒体上にテキスト、イメージ、モデルなどの表現(単数または複数)を物理的に生じさせるための機能性を備えるハードウェアデバイスを意味する。印刷デバイスの例には、印刷デバイスの数あるタイプの中で、インク/トナープリンタ及び/又は三次元プリンタのような印刷デバイスが含まれ得る。
